Hana-Chan is a cute robot dog that can perform a very simple task of detecting foul smell. It comes with a sensor in its nose and smells your feet. If your feet have foul scent then it will emit a warning bark before fainting. If no odour is detected the dog will wag its tail in delight.
Hana-Chan is going to cost you $9,280 and a commercial version of the odour detecting dog will be launched by Next Technology, creator of Hana-Chan.
